Be itknown that L -H WARD M. DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements'in Dyeing-Machines, of whlchithe follow ng is a specification.

My invention relates to a dyeing machine and refers-particularly to, a machine suit- I able for the dyeing or treating of warps in the ball or worsted tops in the ball.

One object of my inventionis a machine adapted to dye vegetable or animal fibers evenly and uniformly. AnotherIob 'ect ofrmy invention is a machine 'adaptecl to dye cotton warps in the ball in a uniform manner. I I I Another object of my invention is a machine u hereby the-condition of the fiber may be readily judged atany stage-of the treating'ope-ration. i

Another object of my'invention is ama chine rvhereby" the dyeing, or other, liquid ma V beuniformly forced through the fiber without disturbingthe fiber.

These'and other objects of my invention will be evident upon a consideration of my pecification and claims;

The principal object to be obtained in" dyeing textile fibersin an inclosed receptacle is the uniform passage of the dye liquor through all parts of the fibers, in,

order that the entire mass maybesubjected to the. same quantity of the liquor. It is further advisable that the temperature of the dye liquorjbe readily determined and easily controlled, as thermost effective re-.

sults of different dyes are obtained at different temperatures.

I have found that the main difficultyfinmachines ,is. due to the tubular 'openings,1the liquor has the natural cident to the even dyeing offfibers' in such"; I

I fa t that whe the I 1 ,d li or isf rced int0theg0OCl$ through tendency'to penetratethelfiber mass in-di rect streams from'the opening, thus subject I ing some portions of the fibers to more'dye' than other liquor I have further found; thisidifliculty maybe overcome, and thatallthe fibers may be sub ected to equal treatment if the perfo:

rations are of a conical or.expanding' 'shapef of such'a formation that the'dye Iliquoriins stead of impinging, upon the fibers in a I distributed with f1 a divergent effect upon the entire'masath'ej series of separate'streams is formation of augmented if not only mation.

portions, resulting-in un- Y u a I channels or liquid, streams through the'fiber being'th'us prevented. I I have also found thatfthis eflf'ect ma be J the entrance per ora- V tionsybut also the exltperforations, for the liquor be of thisconical or expanding ;for-- r '80 fibers' atany per'iod of the treatment operaa tion, Ihave devised asmall machine similar to thelarge one employed fortreatment, so arrangedthat a sample ofthe fibers inserted therein will be subjected to the samerr'e e ment as those in the dyeing machine, and

'hence an examination ofthissample will I disclose the condition of the commercial 1 dyeings without the incident to opening 'I' have also devised a method temperature of the readily observed. v 7

It is evident that when the liquor passes fronrchamberee through the plate l2,it "is not impinged againstthe fiberrin' chamber 45 me series with a direct. upward force, but that,1t-as{ sumes the shape of thepcomcal apertures and of separate streams a .1 20 I is thus spread out and impinged againstitheg a entire lower surface ofthe fiber with a uni-ff form pressure, thus causing it to pass equally through all parts pressure and distribution of the liquor is havingfthe plates- 20,12,16 p and, 18 carry the double conical 'openmgsef maintained by as shown in the drawings- I of the-mass. *An equal a The temperature" of thedye liquor is determined by means "of the thermometer 39 and governed by means of the steam pipe 43.

Before. the dyeingoperation i's'1com-' menced, a proportionate amount of fiberto that in the large device is placed in the small receptacle'33 and the top 35 screw'ed down. During the dyeing operation, some of the dye liquorwill be forced through the 'pi'pe 34- into the receptacle 33 and from there back into chamber 46 through the pipe 36. As

the receptacle 33 and its connecting pipes are exactly proportionate to the larger ones, it

is evident that the results to the fiber'in the receptacle 33 will correspond to those in the larger apparatus, andthecondition of the latter may be readily determined at 'any' water forced through the dyed fiberin the] same manner as the dye liquor above dc;- scribed. 7 v V V I do not limit myself to the si:ze,;shape,.
